IDE cable pinout

40 pin IDC female connector at the Controller 40 pin IDC female connector The IDE interface requires only one cable. All pins straight from 1 to 1, 2 to 2 and so on. The drives can be connected in any order. Only remember that one should be jumpered as Master and the other as Slave. If only one drive is used, jumper it as Single (if such a mode exists, or most common Master else). Controller Drive 1 or 2 Drive 1 […]

Floppy cable pinout

34 pin IDC female connector at the Controller 34 pin IDC female connector The original floppy cable required that each drive was jumpered to the right ID. But IBM come up with an idea to avoid jumpering the floppies.If wire 10-16 are twisted before the last connector the jumpering is avoided. Each drive should be jumpered to act as Drive 2. If only one drive is used then leave the middle connector free.The IDC could also be an edge connector on some […]

RS232 to TTL serial cable pinout

9 pin D-SUB male connector at the computer at the device like a cellular phone i.e. this cable may be used for wiring cellular phone to PC Microcontrollers serial port (often called a SCI, COM, or ASYNC port) often do not generate the proper voltages required for connecting to computer RS-232 serial port. In this case special converter needed. Most microcontrollers run on a single supply voltage, that is usually +5 volts. In rough terms, logical 1 on these devices indicates […]

RS232 to RS485 cable pinout

9 pin D-SUB female connector electrically isolated RS485 communication interface to the PC serial port EIA-485 cable usually made with twisted pair (like EIA-422) and may span up to 1200 metres. The recommended arrangement of the wires is as a connected series of point-to-point nodes, a line or bus. Ideally, the two ends of the cable will have a termination resistor connected across the two wires and two powered resistors to bias the lines apart when the lines are not being […]
